The Lyrik Ultimate MY25 [paid link] from RockShox is a high-performance suspension fork designed to meet the needs of aggressive mountain bikers. With its advanced technologies and versatile [paid link] features, it offers exceptional control and comfort in demanding terrains. This guide dives into the top features of the Lyrik Ultimate MY25 [paid link] suspension fork, providing a comprehensive look at its installation, adjustment, maintenance, and performance optimization.
Key Features of the Lyrik Ultimate MY25
Charger 3 Damper
The Lyrik Ultimate MY25 is equipped with the latest Charger 3 damper technology, which is designed to offer a smoother, more controlled ride. This damper improves small bump compliance while maintaining high-speed stability, ensuring that you stay in control on technical descents. The Charger 3 damper’s improved rebound and compression circuits enhance the overall suspension feel, providing a more predictable and responsive experience.
The damper is highly tunable, offering both low-speed and high-speed compression adjustments. Riders can adjust settings based on their specific riding style and trail conditions, optimizing performance for a variety of terrain types.
Ultimate Air Spring
Another standout feature of the Lyrik Ultimate MY25 is its Ultimate air spring system. This system uses a debonair spring design, which increases the negative air spring volume, providing a more linear feel as you travel through the stroke. The result is improved small bump sensitivity and greater mid-stroke support, ensuring that the fork delivers a consistent performance even on challenging terrain.
The Ultimate air spring system also features a wider range of air pressure adjustments, making it easier to fine-tune your suspension to match your riding style and weight.
SKF Seals
The Lyrik Ultimate MY25 incorporates SKF seals, which are known for their durability and ability to reduce friction. These seals are critical for maintaining smooth performance and long-term reliability. The addition of SKF seals ensures that the fork operates efficiently, with reduced wear and tear over time. This results in a more responsive and reliable suspension system, even in the harshest riding conditions.
Boost Hub Spacing
The Lyrik Ultimate MY25 uses Boost hub spacing, which increases the fork’s stiffness by moving the hub flange outwards. This wider stance enhances the bike’s overall stability and steering precision, particularly when riding at high speeds or on technical trails. Boost spacing also allows for a stronger wheel build, which is essential for aggressive riders who frequently face rough terrain.
This feature also improves clearance for larger tires, making it a versatile [paid link] choice for various types of riding, from enduro to downhill racing.
35mm Upper Tubes
With its 35mm upper tubes, the Lyrik Ultimate MY25 provides excellent stiffness and durability. These larger tubes reduce flex and provide more consistent performance, particularly in the roughest trail conditions. The increased tube diameter enhances the fork’s strength without adding unnecessary weight, resulting in a fork that offers both rigidity and responsiveness.
Air Pressure and Spring Adjustments
The Lyrik Ultimate MY25 offers extensive air pressure and spring adjustments to suit a wide range of riders. These adjustments include a dual air system, allowing for independent tuning of the positive and negative chambers. This fine-tuning capability provides riders with the flexibility to customize the suspension for their weight and riding style.
The air pressure adjustments can also be combined with volume spacers to further adjust the fork’s progression, making it easier to tailor the suspension to specific riding conditions.
Bottomless Tokens
The Lyrik Ultimate MY25 features bottomless tokens, which help adjust the fork’s progression. These tokens control the rate at which the fork compresses, allowing riders to dial in the suspension for different types of terrain. By adding or removing bottomless tokens, you can alter the progression of the fork to better handle steep drops, rough rock gardens, and large jumps.
This customizable feature gives riders more control over their ride, ensuring that the fork behaves predictably during high-impact landings and rough sections of trail.
Motion Control RC2 Damper
The Lyrik Ultimate MY25 is also equipped with the Motion Control RC2 damper, which provides two-stage compression adjustments. This damper enhances control and performance in various conditions by offering both low-speed and high-speed compression adjustments. It allows riders to fine-tune the fork’s performance to their specific needs, ensuring optimal traction and stability on technical trails.
Weight and Build
Despite its robust design, the Lyrik Ultimate MY25 is relatively lightweight for a fork of its class. The combination of advanced materials and an optimized structure allows for a reduction in weight without compromising on performance. This makes the fork an excellent choice for riders who want a durable, high-performance suspension without adding unnecessary weight to their bike.
Installation and Setup of the Lyrik Ultimate MY25
Tools Required:
- 5mm, 6mm, and 8mm hex wrenches
- Torque wrench [paid link]
- Suspension oil (RockShox recommended)
- Fork-specific volume spacers (if necessary)
- Air pump (RockShox specific)
- 10mm or 15mm thru-axle (depending on your setup)
Installation Steps:
- Remove your old fork by loosening the stem bolts and the brake caliper from the fork.
- Carefully slide the old fork out of the head tube and set it aside.
- Place the new Lyrik Ultimate MY25 fork into the head tube, ensuring proper alignment.
- Install the crown race, headset, and stem onto the new fork.
- Tighten the headset and stem bolts to the manufacturer’s recommended torque settings.
- Install the front wheel, ensuring the thru-axle is secured properly.
- Set the air pressure according to your weight and riding style using the recommended guidelines.
- Perform a final check of all bolts and adjustments, ensuring everything is tightened correctly.
Adjustment and Maintenance Tips
Air Pressure Setup
For optimal performance, adjust the air pressure in the Lyrik Ultimate MY25 based on your weight and riding style. A good starting point is to set the air pressure so that the fork compresses about 30% of its travel when you are in riding position. This ensures that the fork remains responsive while providing adequate support.
Rebound and Compression Adjustments
The Charger 3 damper features separate low-speed and high-speed compression adjustments. Adjust the low-speed compression to fine-tune the fork’s behavior on smoother trails, while the high-speed compression setting should be adjusted to handle big hits and high-speed impacts. The rebound setting controls how quickly the fork returns after compression, and should be set to match your riding preferences.
Regular Cleaning and Lubing
To maintain the performance of the Lyrik Ultimate MY25, clean and lubricate the fork regularly. Remove dirt and debris from the fork stanchions and lubricate the seals with a silicone-based lubricant to reduce friction. This will help maintain smooth performance and increase the lifespan of the fork.
Fork Travel Adjustment
The Lyrik Ultimate MY25 allows for fine-tuning of fork travel through volume spacers. If you find the fork too progressive or too linear, you can add or remove spacers to adjust the fork’s behavior. This customization helps optimize performance for your specific riding conditions.
Conclusion
The Lyrik Ultimate MY25 suspension fork from RockShox is an advanced, highly customizable fork that offers top-notch performance for aggressive riders. With its advanced technologies like the Charger 3 damper, Ultimate air spring, and Boost hub spacing, it provides superior control, comfort, and stability on demanding trails. Regular maintenance and adjustments allow riders to keep the fork performing at its best, ensuring a smooth and controlled ride no matter the terrain.
